If the case is as mentioned, her father's reaction is not her fault and will not harm her. He should not do this as she is obeying Allah. Thus, she must not obey him in this regard, because her act of wearing Hijab is an act of obedience to Allah.
Moreover, abandoning Hijab is a sin and no one is allowed to obey anyone in disobedience to the Creator. As for the father, he is sinful in his action. May Allah guide him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
